Diagnostic 15513: Incorrect type of mask parameter of vector variant...
Cause: This diagnostic is emitted by Intel(R) C++ Compiler 15.0 and above. This example uses User implemented vector variant of the function. Traditionally the vector variant of the user defined...

One of the new features in Intel® Trace Analyzer and Collector 9.0 is the new Intel® Trace Analyzer Summary Page. This gives a high-level overview of your program’s time spent in MPI vs. time spent...
View ArticleDiagnostic 15303: routine skipped: no vectorization candidates
Cause: This diagnostic is emitted by Intel(R) C++ Compiler 14.0 and below. This diagnostic message is emitted when the function modifies the ebx/rbx register. Vectorization requires aligned stack...
View ArticleDiagnostic 15309: xxxx was not vectorized: statement cannot be vectorized
Cause: Usage of _Cilk_for or any other threading solution like OpenMP parallel for inside a SIMD loop is not allowed. When such a code construct is enocuntered, the compiler vetorizer emits "statement...

View ArticleDiagnostic 15315: xxxx was not vectorized: low trip count
Cause:By default SSE2 achitecture can fit in 16 characters in one XMM register as a part of vectorization. But in the given example the number of character packed in the XMM register will be 15 and...
View ArticleDiagnostic 15316: loop was not vectorized: not inner loop
Cause:Always the inner loop is targeted for vectorization and outer loop is targeted for parallelization. Below is an example for this scenario.Example:#include<iostream> #define N 25 int main(){...
View ArticleDiagnostic 15321: loop was not vectorized: unsupported loop structure
Cause:This vectorization message is emitted when there are multiple exit points from a given loop. Here the for loop has two different points from the loop (Due to the call to exit(1)) and is not a...
View ArticleDiagnostic 15327: loop was not vectorized: type conversion prohibits...
Cause:This diagnostic message is emitted when a vector type conversion is attempted inside the loop which is not supported by hardware or emulation sequence. The vector type conversions supported...
View Article15330: loop was not vectorized: unsupported reduction
Cause: This diagnostic message is emitted when a loop of below kind is written.Example: int foo(float *A, int n){ int inx = 0; float max = A[0]; int i; for (i=0;i<n;i++){ if (max>A[i]){ max =...

View ArticleDiagnostic 15336: loop was not vectorized: conditional assignment to a scalar
Cause: The loop has an assignment operation of a structure variable whose definition is in vec4.h. Since there are multiple conditions in the process of assignment using this pointer (check the...

Cause:The option -fimf-max-error defines the maximum allowable relative error measured in ulps for math library functions. When this value is set to 0, it looks for a vector version of the math...
View ArticleDiagnostic 15341: loop was not vectorized: nonstandard loop is not a...
Cause: 1. More than one exit point in the loop. A loop must have a single entry and a single exit point. Multiple exit points in a loop can generate this message. 2. This remark is also reported when...
View ArticleDiagnostic 15343: xxxx was not vectorized: insufficient computational work
Cause:This diagnostic message is emitted when the vectorizer detects that this particular computation is better performed in scalar mode.Example: int foo(int a, int b, int n){ int i; for(i = 0; i <...
View ArticleDiagnostic 15377: function can't be vectorized: too many registers...
Cause:Here the return type of the function foo() is complex data type with double which occupies 128 bits. Now specifying a vectorlength(32) clause while declaring SIMD-enabled function, demands 32 XMM...
